1, first, we have to open the computer on the Baidu Music application, into the Baidu Music play the first page, as shown in the picture. 2, randomly open a song, you can search, or hot songs and other forms, to find a song click Play, as shown in the picture. 3, when this song is playing, we look at the bottom of the playback page there is a "listen to similar" button, click it, as shown in the picture. 4, afte

 Delete duplicate records (keep last duplicate data): Delete table where primary key ID not in (select MAX ([primary key ID]) from table group by (duplicate field one + duplicate field two)) Delete duplicate records (keep first duplicate data): Delete table where primary key ID not in (select min ([primary key ID]) from table group by (duplicate field one + duplicate field two)) Finds all duplicate data for a database that does not include the last row of duplicate data: SELECT * FROM table w

Title: Suppose a machine stores only a record labeled ID, assuming that each of the data holds 2 backups, so that 2 machines store the same data. Where ID is an integer: Question 1, at a certain time, if you get a list of data file IDs. Can you quickly find an ID that appears only once in this table? That is, quickly identify the data ID of the failed machine store. Question 2, if there are two machines crash. (assuming that two backups of the same da

[Python] Find and find webshell and pythonwebshell. I wrote a py script to find the webshell left by the server. Previously, we used to list objects recursively. Now we use the walk function, which is faster. The biggest change is the regular expression, which looks quite decent.

Given a binary tree, find all leaves and then remove those leaves. Then repeat the previous steps until the tree was empty.Example:Given binary Tree1/ \2 3/ \4 5Returns [4, 5, 3], [2], [1].Explanation:1. Remove the leaves [4, 5, 3] from the tree1/22. Remove the leaf [2] from the tree13. Remove the leaf [1] from the tree[]Returns [4, 5, 3], [2], [1].The focus of this topic is to prune the tree, and we can use X = Change (x) in the recursive function. F

A typical variant of LCS Algo.The key, the dp[][] array contains enough message to determine the LCS, not only the length, but all of the LCS Candidate, we can backtrack to the find all of LCS.For backtrack, one criteria isdp[i-1][j]==dp[i][j]-1 dp[i][j-1]==dp[i][j]-1Another isdp[i][j]==dp[i-1][j-1]+1 str1[i]==str2[j]Both is OK, this first one is used.//#include #include #include structmynode{intx, y; };#define MAXSIZEintDp[maxsize][maxsize];mynode

I will give it to you later! Don't grieve yourself. Go home for a good meal at night. Body I have always been interested in crawlers and data, and have crawled a lot of data. Of course, c # is required ~~ Today, w

Topic:A sorted array of the given integers, finding the starting and ending positions of the given target values. The run-time complexity of your algorithm must be the Order of O (log n). If the target is not found in the array, then [-1,-1] is returned. For example, given [5,7,7,8,8,ten] and the target value 8,return [3,4]. Idea: This topic directly uses the container to store the location where the find element is found. Remove the first and last

Method One 1. Apple 5s has an application for managing contacts as shown in the following figure. 2. If we enter here to find will be relatively slow, in fact, we can directly click on the "Phone" application. 3. Then you will find a "address book" at the top of the phone panel that we click on to see a lot of apps. 4. If the contact more can enter a word fast search oh. Method Two 1. The abov

MySQL branch), Instead of the original MySQL. In addition, so you run Yum install MySQL is equivalent to running yum install MariaDB But for MARIADB, the direct installation of MARIADB is not going to run as a service, because you only install MARIADB client, so you also need to download a series of MARIADB components than Mariadb-server (server side). Workaround: Run the yum Search all MariaDB A series of packages are then listed Mariadb-bench mariadb-devel mariadb-embedded mariadb-server m

There are many types of stsadm commands, and there are dozens of operation commands (strings after-O), which are hard to remember. I learned one trick today and want to share it with you. In the new dos, a pipe mechanism similar to that in UNIX systems is added. the so-called pipe mechanism is a cross-process processing mechanism that allows a standard output of a process as the standard input of another process (the standard input output refers to the input and output on the screen ). in
